You Will Need

TechTerms
  • aggregation: a group of individuals
  • estuaries: environments where freshwater and salt water meet
  • outfall: the mouth of a drain

Procedure
  1. Go to Save the Manatee Club (http://www.savethemanatee.org/). You should now see the home page of Save the Manatee Club. Look at the photo. Can you see why some people call these mammals sea cows?
  2. Go to West Indian Manatee Fact Sheet (http://www.gate.net/~manatee/manfacts.html). Florida manatees are also known as West Indian manatees. You should now see a page from the Web site of the Manatee Halfway House in Miami, Florida. Use the fact sheet to answer questions 1 and 2 in Part One of the Where Are the Manatees? Data Sheet. You can use the online dictionary to look up words you don't know.
  3. Go to Manatee Recovery Plan Table 1. You will see a table that lists places called aggregation sites. Manatees live in these aggregation sites during the winter. Most of these places are on rivers near generating stations or power plants. As these plants produce electrical energy, they give off waste heat into river water. Manatees like warm water! To get ready for the next step, you can copy the table as a text file, print it, or read it online.
  4. Data Sheet Part One includes a map of Florida and Georgia counties. Use a brightly-colored pencil to fill in the counties that have 25 or more manatees in aggregations. Use a dull-colored pencil to fill in the counties that have fewer than 25 manatees in aggregations.
  5. Create a legend for your map. Show what each color means. Then write a title for your map that includes the term range.
  6. Answer questions 3 through 5 in Part One.
  7. Go back to West Indian Manatee Fact Sheet (http://www.gate.net/~manatee/manfacts.html). Use the fact sheet to answer question 1 in Part Two of the Where Are the Manatees? Data Sheet. The Data Sheet has a map of the eastern United States. Use another colored pencil to shade in the summer range of Florida manatees.
  8. Go to Chessie Who? (http://www.mmsc.org/chessie/index.html). You should now see a page in the Web site of the Marine Mammals Stranding Center in New Jersey. Read about the migration voyages of a manatee called Chessie. You can copy the page as a text file, print it, or read it online. As you read, use an atlas to help you find each location. You can also use the online dictionary to look up words you don't know.
  9. Fill in the legend box next to the map. Show each kind of symbol you used and what it means. For question 2, write a title for your map that includes the term range. Then answer questions 3-5 in Part Two.
  10. Use all the information you collected to answer the questions in Data Sheet Part Three.
